                     ARC Announces New Licensing Agreements
                  with Leading Semiconductor Companies in Asia



     ARC's Configurable Subsystems and Processors Continue to be Adopted by
          Leading Semiconductor Companies in China, Taiwan, and Korea



ELSTREE, England, March 28, 2007 - ARC International (LSE: ARK), the world
leader in configurable media subsystems and CPU/DSP processors, today announced
new licensing agreements with leading Asia-based semiconductor companies.  Each
is a new ARC customer, and all have adopted ARC's patented configurable
solutions to create system-on-chips (SoCs) for high-growth applications such as
multimedia, VoIP phone, and flash memory devices.  See companion news releases
dated March 28, 2007 for more information about two of these new ARC customers.



These license wins underscore the growing number of semiconductor companies in
Asia that are using ARC's configurable products to displace "fixed architecture"
alternatives, and as companion solutions to internally developed CPUs and
processors from firms such as ARM Holdings.  These trends have boosted the
number of license agreements for ARC from semiconductor companies throughout
Asia in calendar year 2006, and led to a record 239 percent increase in revenue
from customers in that region.



"We have been pleased with the strong adoption of ARC's configurable products by
one of the world's largest and fastest growing communities of semiconductor
companies," said Derek Meyer, senior vice president of sales and marketing at
ARC International.  "We welcome these new customers to ARC as they join close to
140 others who are using ARC's configurable subsystems and cores to create SoCs
for high-growth markets."



AD Technology

AD Technology of Korea has selected the configurable ARC(R) 750D core with
associated voice codecs to drive the company's new Power Line Communications
(PLC) SoC.  The PLC chip will provide Internet, phone and other communications
services for a project initiated by the government of the Republic of Korea and
the Korean Electricity & Power Research Institute (KEPR).  See companion press
release dated March 28, 2007 for more details.



Crystal Media

Crystal Media of Taiwan is a fabless semiconductor company devoted to the
development of Internet phone SoC solutions for the emerging VoIP market. An
affiliate of semiconductor foundry giant UMC and founded in 2004, Crystal Media
has taken a license for the configurable ARC 750D core to develop
next-generation consumer VoIP solutions. The ARC 750D core provides Crystal
Media's SoC design team with the ability to increase the performance of their
ARC-BasedTM chip while reducing die size and lowering overall development cost.



Fullhan Microelectronics

Fullhan Microelectronics, ARC's first publicly announced customer in China, is a
leading provider of advanced H.264 video codecs and chips for multimedia
applications. Fullhan has taken a license for the configurable ARC 625D core to
create SoCs for a range of next-generation consumer applications, including
broadband IP set-top boxes, mobile TV solutions, HD DVD, Blu-ray DVD, digital
TV, and digital security surveillance products.



Phison Electronics

Phison Electronics Corporation of Taiwan has adopted the configurable ARC 605
core for the creation of next generation Flash NAND Drives.  Phison selected the
ARC core after a thorough evaluation showed it offers a smaller gate count and
lower power consumption compared to competitive offerings, and because of ARC's
leadership position in the flash storage market for memory devices that
incorporate a 32-bit microprocessor. See companion press release dated March 28,
2007 for more details.
